- Designing a power budget for autonomous turbidity sensor buoysAn autonomous turbidity buoy must collect reliable optical measurements while operating for weeks or months without a service visit. That requirement makes…
- The Relationship Between Turbidity and Particle Settling Velocity in Still WaterTurbidity and particle settling velocity describe different properties of suspended material, yet they are closely connected in lakes, tanks, settling basins,…
- Using Suspended-Solids Sensors for Stormwater Runoff MonitoringStormwater runoff can transport large amounts of sediment in minutes. A short, intense rainfall event may produce a sediment pulse that begins and ends between…
- Groundwater Profiling for Coastal Saltwater Intrusion MonitoringCoastal aquifers supply drinking water, irrigation, industrial facilities, and ecosystems, yet they are exposed to a persistent pressure from the sea. When…
- Integrating Turbidity And Stage Data For Sediment Rating CurvesSediment rating curves translate a measured hydraulic or water-quality variable into an estimate of suspended-sediment concentration or load. A conventional…
- Optical Sensor Maintenance Planning for Year-Round Hydrological MonitoringReliable hydrological monitoring depends on more than selecting an accurate instrument. Optical turbidity monitors and suspended-solids sensors operate in…
- Tracking Sediment Plumes During Deep-Sea Mining OperationsDeep-sea mining can disturb seafloor deposits that have remained stable for thousands or millions of years. When a collector vehicle, suction head, riser…
- How to Convert Nephelometric Turbidity Units to Formazin Nephelometric UnitsTurbidity measurements describe how suspended particles scatter or absorb light in water. The result is commonly reported in Nephelometric Turbidity Units…
- Deploying Turbidity Sensors on Fixed Platforms in High-Flow RiversHigh-flow rivers create demanding conditions for turbidity monitoring. Rapid currents can produce strong vibration, suspended debris, air entrainment, and…
- Managing Natural Organic Matter in Long-Term Turbidity MonitoringTurbidity sensors are often deployed for months or years in rivers, reservoirs, estuaries, coastal waters, and dredging zones. During that time, the optical…
